ACAN, OF

Letters Patent No. 91,919, dated June 29, 1869.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that we, WILLIS DAVIS, of Elizabethport, county ot'Union,State of New Jersey, and GROW- ELL MAcAs, of Railway, county of Union,State of New Jersey, have invented a new and useful Improvement inCarAxle Box'; and we do hereby declare that the following is a' full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being bad to theaccompanying drawings, forming part of this specification.

This invention relates to a new and useful improvement in car-axleboxes; and consists in the novel method of securing the cap of the box,as. will be hereinafter described.

In the accompanying drawings Figure 1 is a side View;

Figure 2 is a front view; and

Figure 3 is aview of the cap detached, shown in cross-section.

Similar letters of reference indicate corres parts.

A is the box, whichis attached to the car or truckponding This box, asis well known, contains the journal of the axle and its bearing, withwaste,. or some absorbent, for holding the lubricating-oil.

For introducingoil to the journal, the cap B has to be removed.

These caps are usually fastened by screw-bolts, and require considerabletime, and cause much trouble in their removal; and as the journals haveto be examined very frequently much-valuable time is lost.

In carrying out our invention we form the cap, as

seen in fig. 3, with fingers G at each side, for slipping over ears onthe sides of the box, as seen in fig. l.

D represents the ears. To prevent the cap from raising by the jarring orvibration of the car, we apply a weighted key, E, as seen in fig. 1. p

F is the bit of-the key, and G is the weighted handle. A key-holeis madein the cap, and the bit of the key is inserted when the handle or weightG is in a horizontal position. When thus inserted the weight drops, byits own gravity, to an upright position, as seen in the drawing, and theprojecting bitprevents the cap from rising.

To-remove the cap, all that is required is to raise the weight G andremove the key, when the cap is raised and removed without diificulty.

This is a safe, convenient, and desirable method of securing the cap ofthe axle-box, and its advantages must be obvious to all concerned in themanagement of rail-cars.

Having thus described our invention,

We claim as new, and desire to secure by Letters Patent- 1. Incombination with acar-axleger O, substantially shown and described.

2. In combination with a car-axle-box cap, the key E, substantially asand for the purposes specified.

The above specification of our invention signed by us, this 22d day ofMarch, 1869.
